Application filed February 19, 1918. Serial No. 218,116.

To all whom t may concern.'

Be it known that I, DONALD McK. HEP- BURN, a citizen of the United States, residing at Akron, in the county of Summit and State of'Ohio, have invented certainnew and useful Improvements in Decarboniz'ing Valves vfor InternalCombustion Engines, whereof the following is a specification, reference being had to the accompanying drawings.

My invention relates to a valve to be applied to an internal combustion engine, and which is adapted to receive and measure a quantity of a liquid decarbonizer and to transfer said decarbonizer to the cylinder while under pressure. To this end my decarbonizing cup comprises a casino' fitted with ahollow measuring cylinder. 'Ihe casing has a funneled entrance and also a discharge aperture leading to the cylinder. The hollow cylinder has non-opposed apertures capable of communicating the one with the funneled entrance and the other with the discharge aperture. These apertures are so Vrelated that when the funneled entrance is opened, the discharge aperture is closed, and vice versa. It is also so arranged that at no intermediate point between the two positions can pressure from the cylinder escapel and blow-through the valve. The hollow cylinder is completely closed except for its'apertures above spoken of, and its hollow interior is of a size to measure a proper charge of the decarbonizing liquid. The interior is of such shape as to permit its contents to completely drain out through the discharge aperture. Y

In order that the turning of the valve may be effective to accomplish its purpose no matter in which direction it is turned, I find it well to provide two discharge apertures one or the other of which will come into service according to which way the valve is turned. Y Y

In the-accompanying drawings, Fig. I, is

la plan view of a decarbonizing valve involving my invention.

Fig. II, is a view of the cylinder and Fig. III :of its washer.

Fig; IV, is` a vertical sectional view through the decarbonizing valve,

Figs V, VI, and VII are cross sectional views along the line V, V, of Fig. IV, showing the valve in three different positions.

The casing 1, is preferably an integral casting which is in the shape of a truncated cone, with its interior forming a ground Joint. toreceive the cylinder 10. Upon the upper side of the casing is a funneledeentrance 2, communicating with the interior of the cup by the longitudinal slot 3. Upon the opposite or lower side of the casin is a discharge aperture 4 directlythroug its wall, communicating with a ldischarge -tube 5, the threaded end 6, of which is capable of being screwed into engagement withthe cylinder to which the device is attached.v

Upon the discharge tube 5, is formed the polygonal nut 7, which enables the device to be screwed tothe cylinder without the necessity of subjecting the functional parts of the valve rand casing to any torsional strain which would be liable to disturb the accurate adjustment of the parts.

The cylinder 10, is preferably ormedas a single hollow casting. Its outer ksurface forms a ground joint registeringaecurately with the'interiorv surfaceof the casing 1. The interior of the cylinder is barrel-shaped the sides sloping from both ends towards the central region in which the dischargev aperture is situated. The interior of the cylinder is of such capacity as to beV capable of measuring oil' the desired charge of decarbonizing liquid, and the sloping sides ensure the complete draining of the V same when turned to its position of discharge.

The hollow cylinder is provided with a slotted aperture 14, capable of registering with the corresponding aperture 3, of the casing, and also with anotheraperture 15 (for discharge) directly throu h its wall, capable of registering with the ischarge aperture 4. It may also preferably be .provided with a `second discharge aperture 16 directly through its wall, which is also capable ,of registering` with the aperture 4, provided the cylinder be turned in the opposite direction.

The larger'end of the hollow cylinder has attached to it a handle 18, which is preferably longer upon oneside than the other, so as to the more conspicuously indicate the position `ofthe valve. The smaller end of the cylinder is prolonged in the form of a stem 20, with a partially ilattened shoulder 21, the remainder 22, being screw threaded forthe' reception of the rounded nut 23.

A special'was'her 25, is interposed between the end of the casing .and its nut. Internally the washer is provided with a flattened surfacev26, capable of engaging the flattened shoulder 21. y'It-is also provided with a recess 28, for the reception of a coiled spring 29, which exerts pressure against the nut 23, ito maintain the washer lfirmly against its seat. The washer has a ground annular surface .30., which fits against the annular end of the casing.

The .exposed larger-end of the hollow cylnder is provided 4with marks, not shown in drawing, which are capable of registering with corresponding marks on lthe larger enel of the casing, to indicate the various positions to which the cylinder Vmust be [turner-1Min order yto perform its successive function; tor, in place of Vsuch mar-ks, suitable ,stops `may be provided.

I. .'Inoperationtbe valve is turned initially vtothe''position of Fig. V, in which the slotted ,aperture .of the hollow-.cylinder registers with the funneled Aentrance, and in this position a measured charge .of decarbonizing liquid-fs'poured in. The funnel greatly asistsxinlthis operation, while the elongated slottedV aperture is useful. lto permit the simultaneous `-entrance of the decarbonizing liquid and the exit .of the air thusdisplaced. In .this position itwillbe noted. that the hol- .low imteriorof the cylinder -is'not in Icommunication with-anything but-'the entrance. ,Bythe rotation of -thehollow 'cylinder to the position shown `in Fig. VI, the entrance is Vclosed. and :the exit opened by `the registry nfaperture 15, with :aperture 4;, :in which. position the measured charge is tree to discharge itself straight through the valvewall directly into the cylinder `notwithstanding :pressure therein which can-not escape because of the otherwisecomplete closure of the' Vinterior of :the cylinder. In passing frem'the position of 'Fig'. V, to that of Fig. "V, there is an intermediate position shown in Fig. CVI'I, in which lthe interior of the cylinder is completely closed, in which polsitia'an `the measured charge may 'be maintained asV long as desired before allowing it to pass into the cylinder."

' Depending upon t'he position of the valve in relation to the cylinder towhich it is attached, it maybe more convenient in operation to turn the cylinder to one side or the other, and inorder that the valve may operate equallfly welll no matter which vvay'it is turned, second aperture '16, f-is Vprovided discharge openings when enabling it to discharge itself when turned in the opposite direction from that shown in Fig. VI.

The ground annular Ajoint between the annular surface 30, of the washer, and the annular end of the casing, is the only gas or vapor-tight joint `formed upon the washer. Accordingly ii' gas escapes from the eXit 4, to .the smaller `end of the hollow cylinder, it readily finds its way out between the surface of the washer on one side, and those oi' the stem and its rounded nut. The provision of such escape is desirable for the reason that a tapered cylindrical ground joint, such as is employed in my dev-ice, tends to wear toward the small end. Gras passing in that direction itnot otherwise free tofesca'pe, will force ythe cylinder slightly out .of its casing, in'order that it may thus escape. Such action is prevented by the vwasher which I have described.

Having thus described my invention,y I claim: f

A decarbonizing'valve comprising a cylindrical casing member anda closed hollow valve member rotatable therein; said casing and valve members having entrance and discharge openings for the reception of liquid and dischargethereoic `to an engine cylinder, and said valve member being otherwise completely closed; thel entrance and discharge openings of said vvalve member beingcapa- Vble of successive, but'not concurrent, registration with those of said casing; and the'entrance aliiorded by registration of valve and casing entrance openings being elongated, so as e'icctually to vent the valve interior o-i air. 4 f
